Objectives #17 (October 24, 2006)
By the end of today’s class, you should be able to do the
* Explain why and how
rocks can undergo metamorphism,
and in what plate tectonic setting it might take place.
* List and describe two major textural changes that occur when
rocks undergo metamorphism.
* Examine hand samples and describe the properties of common
occur in metamorphic rocks. (Examples used in class: numbers 4, 5, 7, 9, 16, 23, 25, 30, 31,
* Examine hand samples of metamorphic rocks, describe their
features, and use a key (textbook p. 73) to identify their names.
(Examples used in class: 101,
105, 115, 116, 131, 140, 147).
* List the names of the metamorphic rocks that result from
metamorphism of sandstone, granite, limestone, and shale, and tell how
each of these protoliths
is different from and similar to the metamorphic rock.
will be due next Thursday, November 2. (The
assignment will be posted later this week.) It will require you
to understand and use measurements of latitude and longitude, and to
know what east and west mean in that context. If you are not
completely confident of your ability to use these concepts, please try
out some of the many helpful tutorials on the web. (Try googling "latitude
longitude tutorial" to find some of them.)
